SPECIFICATIONforming part of Letters Patent No. 404,179, dated May 28,.1889.

Application filed July 11, 1888- To all whom it may concern.-

Be it known that I, GUsTAv JosEF DoL- LINER, manufacturer, of Hamburg,in the Free State of Hamburg/and German Empire, have invented a new anduseful Improvement in Hinged Casements, of which the following is aspecification, reference being had therein to the accompanying drawings.

My invention relates to an apparatus for opening Windows outside andinside of the room.-

Figure l shows a view of the improved window as seenl from the inside.Fig. 2 is a crosssection through the window along the line X X ofFig. 1. Fig. 3 Ais a horizontal section taken through the window in thedirection of the lines Y Y of fFig. 1, with one easement opened outward.Fig. 4 likewise shows a horizontal section taken along the line YY ofFig. 1, with one easement of the improved window when the lower windowgrooved bar, a, is taken out and the easement b is opened inward. Fig. 5shows, on a larger scale, a section. taken through the double hinge g ofthe easement. Fig. 6 shows, on a larger scale, the special constructionof the sockets c and e of this double hinge in such a position that theslanting edges d b', running one upon the other, are just lyingtogether, a position which the parts assume when the window is closed oropened outward. Fig. 7 shows the position of the parts of the hinge,Fig. 6, at right angles to the position of Fig. 6. Fig. 8 shows theboxes or sockets of the hinge parts when the upper part, c, thereof isslid down on the incline d of the lower socket, e, so that theeasement-is lowered to the height of its edge f down on the easement,Fig. 2, a position which is assumed when the Window is opened inward.

The object of this invention, hereinafter described, is to make windowsin such a way that they can be opened both inward and outward, butkatthe same time to combine this possibility with the condition ofobtaining a tight connection between the Window-frame and theclosed-Window easements. In order to attain thisy purpose, each of theeasements has two separate points of rotation, and in addition thedouble hinges of the easements are so made that the easements whenopened Serial No. 279,663. (No model.)

inward descend and the lower window-bar is made to take olf, so that the`easement provided with a strip at its bottom can be drawn inwardthrough the space thus cleared.

The easements b b are-attached to the window-frames h h by double hingesg g. The window-frame h h has at the bottom grooved surfaces e' i, onwhich th'e lower window-bar, v a, is laid. The regular or irregulargrooves 'i 6o serve to prevent as much as'possible the draft gettinginto the room.

The lower window grooved bar, a, is made of two parts, a2 a3, which arealso provided with grooves at their corresponding adjoining edges andfit into each other toothwise, so that the entrance of draft isprevented. The lower Window-bar .has two curved ends, a4, which fitint-o sockets in the Window-frame h. In this way a secure and excellentair-` 7otight and easily-separable connection between the window-bars isobtained. a5 is an appliance for holding one easement so that the closedeasements cannot ily outward.

The veasements are, as already stated, attached to the window-framesby'double hinges g g g g. The double hinges are shown on alarge scale inFigs. 5 to 8. One ange of the hinge is attached to the inner side of thecasement at g. The other flange, g2, runs in a 8o bent form to the outerside of the windowframe h, and there rotates.` about the hingeflange g3,fastened to the window-frame.

If now one easement is to bc opened, it is turned about g3 and pressedoutward, so that 85 it comes into the position shown .in Fig.

If both the easements of one windoware thus moved outward, it is easytotake out the' lower window-bar, a., separated into its two; parts, a2ai. If it is now desired to open the. 9o

windows inward, they are turned about the.v i

part g', as shown in Fig. 4, and they can their' be opened inward.4 'Thehinge parts g', with which the double hinges g areattaehed to thewindows, have tubular sockets c, Figs. 6 to S, 95 which for the greaterpart of their circumference are cut off oblquely or spil-ally. 'lhe sameapplies to the tubular sockets e of the hinge parts g2, eut offobliquely at d. The

object of this arrangement is to lower the roo window to av certainextent while turning about the hinge g', the said extent being lward-turned easement just what the flange f amounts to on the casement.As appears from Figs. 1 and 2, the easements are provided at f and kwith strips or flanges, the object of vwhich is to effect a secureair-tight closure of the window against the window-frame or lowerwindow-bar, a. The height of the upper flange, f, and the descent of theeasementon the oblique surface d are less than the space between thestrip k and the grooves t', so that when the easement' the flange f ofthe window moved inward 'comes and lies inside the window-frame h.

The inward movement of the easement is thus, in spite of the arrangementof the flanges f and k, rendered possible as soon as the lowerwindow-bar, a, is taken out of the window-frame.

In orderi to prevent water from'eollecting on the windows and runningdown them into the lower bar, a, and also to prevent the ease ments inwinter from being frozen in, a lip,

I, is fitted to the inside of the window-case ments below the paires,which catches the water and prevents its running ldown into the lowergrooved bar. i

Between the easement and the Windowframe or the lower window-barindia-rubber or other packing can be placed for the purpose oftightening the easements.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is

1.' The combination of a double-acting hinge, one of whose joints orhinge-points is made with spiral or inclined bearings, a easement hingedthereto, and a removable bottom strip arranged in the opening at thebottom of the easement for the latter to close against, substantially asand for the purpose described.

2. The combination of a double-acting hinge having inclined bearings atone of its articulations, a easement hinged thereto, a removable bottomstrip for the lower part of the casement to bear against, and a lip, l,attached to the lower part of the easementv and overhanging theremovablel bottom strip to catch the condensed water on the easement,substantially as and for the purpose described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
